Among the unused enemies of Super Mario RPG: Legend of the Seven Stars, there is one named Crippo, which is a Hippopo lookalike. It has twice as much health as Hippopo. The only noticeable difference is Crippo's brown and green color and the moves Thornet which could lead the monster to attack itself and Doom Reverb. It is also possible that Crippo's name is a portmanteau of "cripple," referring to them attacking themselves, and "hippo." The unused enemy has no Psychopath thought.
